City
A city is a human settlement of notable size.Goodall, B. (1987) ''The Penguin Dictionary of Human Geography''. London: Penguin.Kuper, A. and Kuper, J., eds (1996) ''The Social Science Encyclopedia''. 2nd edition. London: Routledge. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution. Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for g ...

Hall-Scott
Hall-Scott Motor Car Company was an American manufacturing company based in Berkeley, California. It was among the most significant builders of water-cooled aircraft engines before World War I. History 1910–21 The company was founded in 1910 by Californians Elbert J. Hall and Bert C. Scott to manufacture engines for automobiles and later expanded the production of engines for trucks and airplanes as well as gasoline-powered rail cars and locomotives. Hall was a mechanic and engine builder and Scott, Stanford University-educated, was the business executive. They produced their first rail car in 1909, which they sold to the Yreka Railroad. In 1910, a factory was opened in Berkeley, California, with headquarters for a short time in San Francisco. The company built interurban electric railway cars for railroads such as the electrified Sacramento Northern, which ran trains from adjacent Oakland to Sacramento and Chico. The rail car business was slow, but some were sold as far awa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-sea Rescue Boat
Crash Rescue Boat is a name used in the United States to describe military high-speed offshore rescue boats, similar in size and performance to motor torpedo boats, used to rescue pilots and aircrews of crashed aircraft. During World War II these rescue boats, armed with light anti-aircraft guns for self-defense, saw extensive service with the British Royal Air Force (RAF) and United States Army Air Forces (USAAF). United Kingdom From its inception in 1918 the RAF had seaplane tenders, which as part of Marine Craft Section were used for rescue, but these were really only designed for refueling and rearming the seaplanes in service with the RAF. Development of a purpose-built boat for rescue began in 1932 with the 200-class seaplane tenders, followed by the 100-class ASR ( Air-Sea Rescue) boats which entered service in 1940. Perhaps the best-known 100-class boat was the 36-knot (67 km/h) British Power Boat Company Type Two 63 ft HSL, also known as the 'Whaleback' after its dist ...

Anti-aircraft
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraft ...

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Packard
Packard or Packard Motor Car Company was an American luxury automobile company located in Detroit, Michigan. The first Packard automobiles were produced in 1899, and the last Packards were built in South Bend, Indiana in 1958. One of the "Three Ps" alongside Peerless Motor Company, and Pierce-Arrowthe company was known for building high-quality luxury automobiles before World War II. Owning a Packard was considered prestigious, and surviving examples are found in museums, car shows, and automobile collections. Packard vehicles featured innovations, including the modern steering wheel, air-conditioning in a passenger car, and one of the first production 12-cylinder engines, adapted from developing the Liberty L-12 engine used during World War I to power warplanes. During World War II, Packard produced 55,523 units of the two-stage/two-speed supercharger equipped Merlin V-12s engines under contract with Rolls-Royce. Packard also made the versions of the Liberty L-12 V-12 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Auxiliary Motor Minesweepers
Auxiliary motor minesweepers were small wood-hulled minesweepers commissioned by the United States Navy for service during World War II. The vessels were numbered, but unnamed. The auxiliary motor minesweepers were originally designated yard minesweepers (YMS) and kept the abbreviation YMS after being re-designated. The type proved successful and eventually became the basis for the AMS type of United States Navy minesweeper. Origin of the YMS The Henry B. Nevins Shipyard, Inc., at City Island, Bronx, designed the YMS and laid the keel of the first one, , on 4 March 1941. Launched on 10 January 1942, ''YMS-1'' was completed two months later on 25 March 1942. From keel-laying to completion, the yard built ''YMS-1'' in one year and three weeks. The "Y" designation The first wooden minesweeper of this class was to gain prominence in all theaters during World War II. A total of 561 were built at various U.S. yards. Originally a class of "motor minesweepers" (MS), "Y" was add ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adjutant-class Minesweeper
The ''Adjutant''-class auxiliary motor minesweepers were built for the United States Navy throughout the 1950s and 1960s, even as late as 1978. Most were loaned to foreign countries under the Military Defense Assistance Pact, with only 24 actually commissioned by the US Navy, with 13 of those eventually being transferred to foreign nations as well. Initially classified as auxiliary motor minesweepers (AMS), on 7 February 1955, they were reclassified as coastal minesweepers (minesweeper, coastal) (MSC). Design The ''Adjutant''-class minesweepers were of a wooden construction with brass and stainless steel fittings to reduce magnetic attraction. The rated displacement was light and at full load, though the ships of the ''Redwing'' class show a displacement of and the ''Albatross'' class show a displacement of . They were between the perpendiculars with an overall length of . They had a beam of with a draft. Half of the US ships used four Packard diesel engines. The res ...
